Product Description

Yueli 400 four-axis CAM turntable

CAM type zero back backlash CNC rotation

Factory Direct Sale Quality 400 Four-axis CAM Turntable Manufacturers and Suppliers. YueLi is 400 Four-axis CAM Turntable manufacturer and supplier in China.

Cam-roller transmission structure is adopted inside the product.

CAM shaft needle roller bearing precompression no gap rolling drive.

No sliding friction, continuously maintain no gap characteristics.

High accuracy of forward and reverse motion repetition.

High rigidity, high efficiency.

Does not cause poor accuracy due to temperature rise.

No need for regular calibration and adjustment.

Working principle and characteristics of cam-type CNC turntable

Principle of preloading

Compared with the traditional worm gear type NC turntable, the grating CAM type NC turntable has higher precision

Operating characteristics of degree, high speed, zero back clearance and heavy load. Input axial cams

The needle roller bearing on the output shaft turret of the constant speed driving curved surface is precompressed rolling contact transmission,

To achieve zero back backlash and higher speed operation, due to the rolling transmission almost zero

Friction movement, so that the mechanism can maintain no backbacklash transmission, high precision positioning, and no need

Regular calibration and adjustment work should be done. Lattice CAM type CNC turntable, Han out of the shaft use

The large bearing is arranged on the round outer wall of the shaft, and the two ends of the CAM input shaft are set with double bearings.

It also enhances the stability and load capacity of the turntable, and can better cope with the processingHigh speed and heavy cutting force, improve machining accuracy, efficiency and reduce costs.
